ceases.

To all whom it 'may concern:

it known that I, CARL C. MADSON, a citizen of the United States, residing at 'Lanesborm in the county of Fillmore and State of Minnesota, have invented certain new and useful Improvements in ice-Making Appliances, of which the following is a speci side of an outer chambenawhich latter may ator, accordingly be opened or closed at the will of the operas the ice is 'being formed. o r harvested.

My invention further consists in certain novel features of construction and combina# tions ofL-Aparts whichl will be hereinafter describedand pointed out in the claims.

' In the accom anying drawings z-Figure 1 is a view iii si e elevation. ,Fig..2 is .a horiT zent-al section. Fig. 3 is a transverse section.

A, represents a metal tank. This is of any size and dimensions and 4preferably lsupported on the bottom on suitable cleats l, l, placedat intervals apart for its support, and whereby to afford air or steam space beneath the tank. The framework l5, is'constructed outside ot' the tank, consisting of -21 4 sills and uprights as shown.' '5A `iacket or casorted upon the frame work which consists o a Hoor 2 formed at` the bottom of :the frame and the' sides are in theorm of Idoors 3, 3, hinged preferably at the bottom.

as at 4, 4. The jacket surrounds the bottom, sides, and one end of the tank, and as the tank is supported out of contact with these parts, steam can be admitted for thawing the icein the tank. The upper .edges of the sides of the tank rest upon the top of the frame-work or'jacket. The object of these I 'right position foi melting harvest the ice. The ice is formed in the tank by. any of the sides of the metal tank w en it Ais desired to approved methods of manufacturing ice, as

and harvesting of the ice more than with its formation.

As a simple means for separating the ice into cakes of suitable size, the hollow partitions 5, 5, are employed. These are located to suit the requirements as to size of theblock of ice, and a steam pipe 6, 6, discharges into each partition, whereby the ice formed in contact with the partition is loosened just .as at the sides where the doors are located.

A water-tight door 7 having a gasket extending over one side may be provided at one end of the easing for closing the tanky which is open at this end, and through which the ice is pulled out after being frozen. Also the ice might be lifted 'out througlithe top, if desired, by any convenient mechanism for that purpose.

The steam for loosening the ice from the sides of the tank is introduced through pipe 8. i

From the foregoing it will be seen that it is simply necessary to close the doors at the sides and turn onthe steam in pipe 8 ,to loosen' the ice from the sidesof the freezing tank, and togturn the steam into pipes 6, 6,

to loosen the ice in contact with the partif' tions, after which it'may be removed 1n any" convenient manner, either from the top or In this for loosening and vremoving the icc, thus greatly reduclngthe cost and the time cons umed in liberating the frozen product from the tank in which itis formed, and in which it is tightly frozen. v

t is evident that more or less slight changes might be resorted to in the form and arrangement of the several arts described Without departingfrom t e spirit and sco e of my invention, andhenee I do not. wish to limitmyself to the-exact construction herein s 'et forth, but

Having lly'described my invention, what claim as new and' desire tosecure by, Letters Patent, is

41. The combination' Awith a jacket hav-ling a bottom, cleats vupon the bottoni, of a tank mounted upon the cleats forming a space between the bottom of the jacket and tank,

doors hinged to the bottom adapted to be raised alongside the sides ofthe tank'or forming-the sides of the casing to form a .Space between the ank and sides of the easing, said space between the Casing and the Mink adapted to receive a `iii-wing medium for libeizitin the ice in the ltank.

2, The combination with a jacket havin botom, oeas upon die bottom, of a tm mounted upon the cleats forming e space between the bottoniof the jacket and tank, doors hinged to the botom adapted to be raised alongside the sides o the tank `for forming the sides of ne casing to orm e space between ehe ank and sides of the casing', said space between he casing and 4une tank adapted to receive a thawing medium for iiberazing the ice in the tank, and hoiiow partitions in die tank for separating he ive into -sni'aioie sized blocks, sind partifaz-seas@ CARL C.
